This study evaluated the effect of an school-based oral health program supplied to primary school children in Anyang city. This program included oral health education, pit and fissure sealing, fluoride mouth rinsing and professional tooth brushing. The numbers of the subjects were 311 children in the program participant group and 165 children in the control group which were not in the program. Data were analyzed with t-test, one way ANOVA and pearson's correlation coefficient using SPSS WIN 12.0 program. In attitude, behavior of oral hygiene, participant group was better than the control group. In case of the perceived oral health, satisfaction of oral health, need oral treatment there was no significant difference between the two groups. These results suggest that school children can learn the good attitude and behaviors and oral health promotion can be achived from the oral health program run by shool dental clinic.

The purpose of this study is to analyze the factors affecting the education experience, education needs, and knowledge level of calculation criteria for dental workers. It was conducted on dental workers in Daegu and Gyeongbuk province and an online survey was conducted using Google Survey. We used frequency analysis, crossover analysis, and ANOVA analysis method to find out general characteristic, education experience, education needs, and knowledge level according to education experience and education needs of candidates. As a result of in the knowledge level survey of dental health insurance, there were high rates of incorrect answers to the calculation criteria when the claim program automatically processes it or notifies you through an error window. The level of knowledge of candidates who are experienced, on a claim, and with experience in dental insurance training in the last six months was high. In conclusion, it seems that accurate and correct insurance claims are possible when the dental workers are familiar with the calculation criteria changed through regular dental health insurance education. We look forward to this study providing basic data in preparation of education system for professional dental insurance claims for dental workers.

현재 S회사의 생산공정은 전 과정에 걸쳐 통합된 정보처리 체계가 없고, 생산계획 및 통제 과정에서의 복잡한 계산 및 중요한 의사결정이 담당자의 경험적 지식에 의존하고 있다. 이러한 상황의 한계로, 현재의 생산공정계획 및 생산실행계획은 시간적 제약이 크고, 유연적인 수정이 어려울 뿐 아니라, 통계적 분석의 자료체계가 부실하다. 그러나, S회사는 보다 개선된 공정관리를 위해 새로운 생산계획전략의 필요성을 느끼고 있다. 본 논문에서는 이러한 문제를 해결하기 위한 하나의 접근방법으로써 DEVS 형식론을 바탕으로 공정을 효과적으로 모델링 및 시뮬레이션화 하였다. 생산계획의 핵심부분인 전문담당자의 경험적 지식을 체계적 규칙으로 정리하여 모델에 반영하였고 이를 통해 습득된 시뮬레이션 결과를 분석하여 생산계획 전략의 신뢰할만한 평가기준을 마련하였다.

Determination and optimization of proper welding condition are very important tasks to be directly related to weld quality and productivity. On this research the relationship between welding parameters and results is investigated systematically. Theoretical method, statistical analysis of experimental data and analysis of empirical knowledge are applied for this work. These results are represented by empirical equations, fuzzy rules and artificial intelligent knowledge forms in the knowledge base. The approximate reasoning of fuzzy expert system and the information in the knowledge base are used for recommendation of suitable welding condition, and optimization of welding parameter which is based on the evaluation of welding results by user.

최근 대학의 진로지도는 재학생들에게 산업 현장에서의 경험을 제공함으로써 학교에서 배운 전공지식을 기업현장에 적용하여 전공과 관련된 실무경험을 축적하는데 초점을 맞추고 있다. 이러한 맥락에서 대학에서의 현장실습은 더욱 강화되고 있는 추세이며 이를 통해 학생들이 습득하는 산업현장에 관한 경험, 정보와 아이디어가 진로에 대한 자신감을 향상시켜 졸업 후 고용획득 뿐만 아니라 창업의 동기로 작용하기도 하는지 확인하는 것은 중요하다고 할 수 있다. 본 연구에서는 진로에 대한 자신감을 향상시켜 이에 따른 행동을 이끌어 내기 위한 동기적 측면에 관한 연구를 수행하고자 한다. 이와 함께 능동적이고 계획적으로 진로를 선택해 나가는 자기주도적 경력태도와 기업가정신에 따라 현장실습경험이 고용가능성과 창업의도에 어떠한 영향을 미치는지에 대해 분석할 것이다. 본 연구에서 예상되는 주요결과는 다음과 같다. 첫째, 대학생의 현장실습 경험은 대학생이 인식한 고용가능성에 유의한 영향을 미치며 창업의도에도 직접적으로 영향을 줄 것이다. 둘째, 대학생의 자기주도적 경력태도는 현장실습 경험에 따른 고용가능성과 창업의도 사이에 유의한 영향을 미칠 것이다. 셋째. 대학생의 기업가정신은 현장실습 경험에 따른 고용가능성과 창업의도 사이에 유의한 정(+)의 영향을 미칠 것이다.

Data mining is the process of extracting hidden patterns from collected data. At this time, for collected data which take important role as the basic information for prediction and recommendation, the process to discriminate incorrect data in order to enhance the performance of analysis result, is needed. The existing methods to discriminate unexpected data from collected data, mainly relies on methods which are based on statistics or simple distance between data. However, for these methods, the problematic point that even meaningful data could be excluded from analysis due that the environment and characteristic of the relevant data are not considered, exists. This study proposes a method to endow human heuristic knowledge with weight value through the comparison between collected data and human heuristic knowledge, and to use the value for creating a decision tree. The data discrimination by the method proposed is more credible as human knowledge is reflected in the created tree. The validity of the proposed method is verified through an experiment.

The period after the PhD has a huge impact on the careers of researcher from a researcher lifecycle perspective. This is a turning point which student receives guidance from professor and become an independent researcher. Furthermore, they learn to develop ideas for independent research, apply for grants and manage a project; they also form expert networks in related filed and publish papers to share their findings. This study focuses on the period between earning doctoral degree and being employed as a stable position in university. This study starts from a research questions that asks which factors of postdoctoral experience affect research output. In this study, the paper performance, especially co-authorship of paper, of postdoctoral researchers was investigated. The cumulative advantage theory and Matthew effect were employed to shed a light on this research question. The empirical work is based on the Survey & Analysis of National R&D program in Korea conducted by Korea Institute of S&T Evaluation and Planning (KISTEP). The correlations between the research output and characteristics of postdoctoral experience were verified. These results are expected to contribute as new empirical evidences on investigating knowledge transfer activities of new PhDs.

The purpose of this study was to suggest an instructional direction for improving scientific problem-finding ability. For this purpose, the present study made an in-depth analysis about activity on problem finding tasks of high school students in an ill-structured scientific problem situation. Subjects were divided into two groups (cooperative and individual) and two kinds of problem finding tasks were administered to two groups. Results indicated that a cooperative activity on problem finding happened to a series of steps exploring problem situation, expressing knowledge and experience, discussing provisional problems, creating various problems and selecting the best problem. Besides, a cooperative activity on problem finding depended heavily on prior knowledge and experience, and in the meantime, various scientific concepts turned out to naturally be expressed. As for the problems found out during a cooperative activity, their scores in creativity factors, including the degree of agreement in original problem selection came out to be on the whole, as excellent. In addition, the types of the problems found out in open problem situation showed that they were more various than those found out in closed problem situation. Subjects perceived that activity on problem finding had positive influence on scientific concept and science process skills. Findings of this study have the following educational implications: First, it is needed to prepare for educational environment that enables students to explore various knowledge and information. Second, the offering of various opportunities is needed to enlarge the scope of scientific knowledge and experience. Third, it is needed to prepare for a study atmosphere that lets students express their knowledge and experiences freely.
